Write the Matrix Equation as a System of Linear Equations

Multiple Choice

Write the matrix equation as a system of linear equations without matrices.
- $$\left[ \begin{array} { r r } 8 & - 8 \\- 8 & 4\end{array} \right] \left[ \begin{array} { l } x \\y\end{array} \right] = \left[ \begin{array} { l } 8 \\8\end{array} \right]$$

A) $8 x - 8 y = 8$
$- 8 x + 4 y = 8$
B) $8 x - 8 y = - 8$
$- 8 x + 4 y = - 8$
C) $- 8 x + 8 y = 8$
$- 8 x + 4 y = 8$
D) $8 x - 8 y = 8$
$4 x - 8 y = 8$
